Recording medium, method and computer for executing a shooting game in an entertainment system

Abstract

A method and a computer for executing a shooting game which is played by a user using a controller to enhance the nature of the game without eliminating its rapid-fire function. The computer that executes a shooting game includes a controller having a pressure sensing unit that detects an operation pressure by a player during a shooting operation, a unit that determines the number of projectiles to be shot according to the pressure in the shooting operation detected by said pressure sensing unit, a unit that shoots the determined number of projectiles to be shot by a player character on the monitor, and a unit that decides whether the enemy character has been shot.

1 . A recording medium on which are recorded shooting game software programs, including programs that process as commands an output from a controller that has a pressure sensing means, that can be read and executed by a computer, to which the controller is connectable, wherein 
 said software programs include processing programs that shoot projectiles in a screen of the computer in a number that corresponds to said output of said controller.    
     
     
         2 . The recording medium as described in    claim 1   , wherein a number of said projectiles to be shot per unit time is varied according to a rate of change per unit time of an output value of said controller.  
     
     
         3 . The recording medium as described in    claim 1   , wherein the number of said projectiles to be shot per unit time is varied according to the size of the output value of said controller.  
     
     
         4 . A method for executing shooting games on a computer by using a pressure-sensitive controller, comprising the steps of: 
 detecting a pressure by a user in a shooting operation, by a pressure sensing means provided on the controller,    determining a number of projectiles to be shot in accordance with said pressure in the shooting operation, detected by said pressure sensing means;    shooting a determined number of projectiles to be shot by a user character on a monitor at the computer; and    deciding whether an enemy character has been hit.    
     
     
         5 . The method as described in    claim 4   , wherein in the step in which the number of projectiles to be shot is determined in accordance with the pressure in the shooting operation detected by said pressure sensing means, the number of projectiles to be shot is determined in accordance with a rate of change per unit time of the pressure in the shooting operation.  
     
     
         6 . The method described in    claim 4   , wherein in the step in which the number of projectiles to be shot is determined in accordance with the pressure in the shooting operation detected by said pressure sensing means, the number of projectiles to be shot is determined in accordance with an amount of the pressure in the shooting operation.  
     
     
         7 . The method described in    claim 4   , wherein in the step in which the number of projectiles to be shot is determined in accordance with the pressure in the shooting operation detected by said pressure sensing means, 
 the number of projectiles to be shot is determined in accordance with a rate of change of the amount of the pressure in the shooting operation in a previous time and the amount of the pressure in the shooting operation at the current time.    
     
     
         8 . A computer that executes a shooting game in an entertainment system comprising: 
 a controller having a pressure sensing means that detects an operation pressure in a shooting operation by a player playing the shooting game    a means that determines a number of projectiles to be shot in accordance with the operation pressure in the shooting operation, detected by said pressure sensing means;    a means that shoots the determined number of projectiles to be shot by the player character on a monitor of the computer; and    a means that decides whether an enemy character has been shot.    
     
     
         9 . The computer as described in    claim 8   , wherein the means that determines the number of projectiles to be shot in accordance with the pressure of the shooting operation detected by said pressure sensing means 
 decides the number of projectiles to be shot in accordance with a rate of change per unit time of said operation pressure of the shooting operation.    
     
     
         10 . The computer as described in    claim 8   , wherein the means that determines the number of projectiles to be shot in accordance with the operation pressure in the shooting operation, detected by said pressure sensing means, 
 decides the number of projectiles to be shot in accordance with an amount of the operation pressure of the shooting operation.    
     
     
         11 . The computer as described in    claim 8   , wherein the means that determines the number of projectiles to be shot in accordance with the pressure of the shooting operation detected by said pressure sensing means 
 decides the number of projectiles to be shot in accordance with a rate of change of the size of the operation pressure in the shooting operation at the previous time and an amount of the operation pressure at the current time.
